METALLIC sHoE FOR TOBOGGAN'S.

EPECIPICATION forming part of Letters Patent No. 353,547, dated November 30, 1886.

Application filed May 28, 1686. Serial No. 203,507.

To all whom it may concern;

Be it known that I, CHARLES H. EMERSON, a citizen of the United States, residing at Yonkers, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Metal Shoes or Runners for Toboggans and Ooasting-Sleds,-of which the following is a specification, reference being had to the accompanying drawings, forming part thereof. I i

The objects of my invention are, first, to provide a light flexible metal shoe of thinner material than is practicable where screws, bolts, or rivets are used as heretofore; second, to protect the edges of the shoe against abrasive and retarding contact with ice or snow,

and, third, a ready means of fastening the shoe without the use of such fastening devices as screws, bolts, or rivets anywhere through its bearing-surl'ace I attain these objects by the devices illustrated in the accompanying drawings, in which Figure l is a longitudinal side view of the shoe; Fig. 2, a cross-section of the shoe; Fig. 3, a cross-section of aslatof atoboggan or runner, showing grooves into which portions of the shoe are drawn Fig. 4, a cross-section of a toboggan-slat or sled-runner, showing another way of fastening the shoe by means of a piece of wood fastened to the bottom of the toboggan or sled to hold the shoe in place.

My fleirible shoe is provided with flanges throughout its length, as shown at A and D, they being turned upwardly in any suitable manner so as to enable them to snugly embrace portions of the wood which overlie the shoe when applied to the slat or a runner ofa coast' ing-sledoratoboggamandthus enablesaid shoe to be properly confined in position without the aid of screws, bolts, or rivets at or adjacent to any part of its bearing-face.

In Fig. 31 show in section a slat or runner which is provided with longitudinal grooves G G,'which are inclined toward each other laterally throughout the wholelength ofthestraight portion of the runner, and the flanges A and D snugly occupy said grooves, and thus cause the portion E of said runner to be firmly embraced by the shoe. The front end, B, of said shoe is not flanged, thus providing for its being more readily bent or curved upwardly to conform to (No model.)

grooves at their ends, and then the shoe is either drawn forward or the runner forced longitudinally until they occupy theirproper relative positions.

The shoe may be fastened by the use of the piece-I, Fig. 4, which is itself fastened against the bottom of the toboggan in any suitable way, in this case by the screw H, using as many of these pieces as the length of the toboggan may'require; or one continuous piecemay be used shaped so as to be embraced by the flanges of the shoe. The piece of metal may be wide enough to cover the whole under surface of the slat or runner and have its edges turned inwardly and down upon the upper surface of the slat to hold it in place; or the piece I may be covered by the steel or metal at one operation, as when drawn through a die, and then secured by means of screws from the upper side.

I prefer the grooves F and G, first, because this method securely protects both sides of the turned-up edges of a light thin shoe, with the least additional weight, against abrasive and retarding contact with the ice or snow, and prevents any foreign substance from working between the shoe and the wood, which would be liable to wedge them apartand cause humps and irregularities of surface, which would quickly happen with thin shoes if put on in the old way and secured by screws, rivets, orbolts passing through the face of the shoe; and, second, because the turned-up edges being firmly held on both sides by the sides of the grooves extra or additional stiffness is imparted to a 5 thin shoe without materially impairing the desired flexibility of slat or runner.

though two only ma results.

What I claim as nayinvention and desire to secure by Letters Patent, is ner provided with longitudinal grooves on its 1. lhe combination, with the wooden slat or 1 under surface and a flexible metal shoe having runnerin acoasting-sledortoboggan, of afleXiupwardly-turned flanges which occupy said ble metal shoe flanged at its edges and snugly grooves, substantially as described.

embracing overlying portions of the wood CHARLES H. EMERSON. throughout the length of the shoe, substantiall'y as described, whereby the main orbearingportion of said shoe is confined in position y be used with very good bolts, or rivets at any point throughout the bearing of the shoe.

2. The combination of a Wooden slat or run- Witnesses:
